[Q] Nexus 4 Battery Drain - Nexus 4 Q&A, Help & Troubleshooting

Recently i noticed that my phone's battery begin drained at night during sleep like about 20% without any use.
i did turn off location services, Wi-Fi, GPS. I don't know what could be the problem for the battery to be drained.
Is there a way to check it?

Use BetterBatteryStats to find the issue. Do you use s2w or touch control? They drain some battery too

:silly:

I checked battery in Settings and it shows 41% Phone idle and 26% Cell standby.
So i don't think Google Services is the problem here...

I used to have a problem like this, install better battery stats and it will show exactly what is draining you battery, for me it was nfc being left on.

Gotta figure out your wake locks. I lost 0-1% overnight last night.
Best bet is to download better battery stats and gsam battery info. Also CPU spy is helpful for figuring if your tablet is deep sleeping or not.

Also turn off NFC and WiFi. That will help a ton

I've turned off NFC, Location Services and only sync the folders I need in Gmail and i'm down to about 5% overnight. I'll try setting the wifi to sleep when the screen is off and see how that goes.
How accurate are battery stats on the Nexus 10?

Battery issues with 4.2.1?

Hello-
Ever since I updated to 4.2 and especially 4.2.1, battery life has not been the same. Today I went from 100% last night to 73% in 22 hours just in standby. I didn't change any settings that I can remember. Can anyone please help with this?
Thanks,
wws12

I had the same battery issues on 4.2 in standby...even with wifi disabled. I ended up flashing back to 4.1.2 and battery is back to normal. To me 4.1.2 is more stable and much smoother. Hopefully Google will fix these issues in the next update.

I noticed that a large portion of the battery is being used by something called "Media server" Any idea what that is or how to turn it off?

I'm also noticing the same sleep mode battery drain on 4.2.1,around 1% per hour..

Use media scanner root from the play site and disable the media scanner. Then this battery drain should reduce.

I think in my case most of the battery issues was from the device being new and the software stats still needed more time to be accurate, that has happened to me on my Sony tablet also..
Now I can see some real stats as I use better battery stats app for keeping track of the battery.
I use my tablet as a use when needed device because it's not my notifications device that is always connected, for that I use my smartphone. That said I turn on airplane mode when I'm not using it and sync when needed as well.
Só when my Nexus 7 is in sleep mode it has very few apps and services running other than the system ones.
So the stats I came up with are:
1% in sleep mode with airplane mode on and Google Now and Location History turned on..
And..
0.3% in sleep mode with airplane mode and Google Now plus Location History off..
So for me no Google Now as I don't need that much.. It lasts 3x more in standby without it... And the truth is, in my country Google now for me isn't that useful as it is although I'm sure someday will be..

It's strange...with stock 4.2.1 no root I haven't any battery drain... 0.7% /hour with wifi on and sync enabled...In the battery stats, even if in a hour i turn on the display on a minute, the display takes at least 40% of battery...

wow guys are you all serious??? i lose around 10-15 percent overnight man
Dude.. My phone was on 60 percent at 6pm once when I slept... Next morning at seven it was off... Wifi off data off.. All **** off... I dint even get a call or msg... Definitely not 1 percent I guess...
If I leave data and WiFi off, about 2% to 10% but that isn't usual. When I am home, I leave WiFi on and that gets my currents and YouTube video preloaded. 15% to 20% Max. I rarely leave it to charge overnight.

I woke up with 15-20% battery drained... wtf guys ?
I kill all apps, turn of data, wifi and etc, still nothing...
BATTERY STATUS - messaging use 84% of battery... wtf ?
To all of you having problems with battery drain, you should know that last Google Maps update messed up the deep sleep state of the system.
I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.
I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.
With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Android System" or "Google Services".
Before update I had around 3% battery drain over night(around 8 hours) with WiFi.
Hope this helps.
:fingers-crossed:
As a battery life druggie, I get 1% max. Regardless rom. Usually wifi off and 2g data on. (wifi on is bad for HUMAN DEEP SLEEP).
A not sure useful or not hint, set pm.sleep_mode=1 in your build.prop
Disable everything you can think of. Wifi, gps etc.
Uninstall bloatwares, replace with downloadable ones, use greenify to freeze them.

Nexus 7 battery drain overnight

I purchased a nexus 7 recently,updated to 4.3,locked and unrooted as of yet. I currently have 2 user accounts active on it. Since my first 100% charge, I have been getting tacky battery life. I follow the 100% charge and discharge till 1% method. Overnight with WiFi on and all apps closed,I'm getting a drop from 74% to 57% . Looking in the battery stats doesn't help as it doesn't show any unusual ongoing background activity. I'm also getting around 6 hours Screen on time,I could never exceed this mark. I only have the customary Google apps,Facebook,Twitter, instagram,pulse,and 3 games installed. What can be the reason of this ?
Sent from my Nexus 7 using xda app-developers app
Those apps keep running.. Also some third party apps push ads and also turn screen on, which could drain battery..
For better battery life, you can turn wifi off if not needed,.

I tried with WiFi off one night, I got around 9% drain still. I kept the sync interval at the maximum in every data fetching app I have installed too.
Sent from my Nexus 7 using xda app-developers app
You might well try the app Better Battery Stats, and see what it believes is keeping your tablet from going into deep sleep. 9% drain overnight is not terribly excessive -- it should be more like 5%, I guess.
My 2012 nexus 7 had 51% before I went to sleep last night and when I woke up this morning it was completely dead. I didn't even get a charge icon when I plugged it in to charge. I had to leave it for an hour then tried again and it fired right up.. Hope I can see what's causing the drain with better battery stats
Sent from my Nexus 7 using xda app-developers app
I was using mine once in the morning,when the battery hit 4% it suddenly shut down. I tried to charge but the battery icon wouldn't show up. Started it finally using the tips on the Google support site. Must say,I've been plagued with battery issues. I'll try a factory reset and while on it unlock the boot loader too.

I checked with BBS with WiFi off overnight. "PowerManagementService.wake lock" is keeping my N7 awake. Any solutions?
EDIT: I checked in partial wakelocks,AudioOut_2 was the highest at 30m runtime.

Did you mean when the screen is off? Because obviously it status awake while the screen is on. But there may be an app keeping it awake. Make sure all your apps are trusted

and all the apps ive downloaded are from Google Play Store of course.

I'd go for a wakelock detecting app like "better battery stats" or "wakelock detector" to see which app could be the culprit. "Greenify" could then be used to block that app from keeping your tablet awake.
I personally do have no issues with standby whatsoever. I'd say I lose about 3-4% of battery during the day on 4.4. (WLAN and sync on all day, but I'm taking it to work where I have no WLAN I could use). I guess I had the same mimimum drain on 4.3. So standby couldn't be better on N10 in my opinion.
I only had one issue so far, where at about 25% of battery left it suddenly began to drain like 10-15% an hour, thus leading to my N10 shutting off after about 2 hours. No idea what caused that drain in standby.
I second that, get better battery stats or something similar to see what's keeping it awake.

mhm ... will not install 4.4 if the battery life is that terrible. Did you guys control the typical Google apps, which usually like to eat a lot of battery?
I have this since 4.4.2 on my Nexus 10 and 7v2. Not on the 5. My N10 uses almost every juice for Android OS. Before it used 5% for 1-2 days for standby. Now 3 hours. See screenshot. Is this normal?
And it wasn't awake. See other screenshot.
